Researchers from the University of Maryland School of Nursing and the Johns Hopkins University School of Medicine examined data from 71 Illinois and North Carolina hospitals and found that “patient deaths from pneumonia and acute myocardial infarction were significantly more likely in hospitals where nurses reported schedules with long work hours,” reports Laura Walter in EHS Today. (The study itself appears in the January/February issue of Nursing Research.)

During nursing shortages in the 1980s, many hospitals switched nurses from 8-hour shifts to 12-hour shifts, and the pattern has persisted. While many nurses appreciate being able to fit an entire week’s work into a few days, the practice may not be good for patients – or for the nurses themselves. Study author Alison Trinkoff explains that “alertness and vigilance required for providing good nursing care depend upon having an adequate duration of quality sleep and rest.” Walter notes that in a previous study, Trinkoff and colleagues found that a lack of time off contributed to nurse injury.
